Insecticide Resistance in the Western Flower Thrips, Frankliniella occidentalis
Integrated Pest Management Reviews, 2000The western flower thrips, Frankliniella occidentalis Pergande (Thysanoptera: Thripidae) is a serious pest on a wide range of crops throughout the world. F. occidentalis is difficult to control with insecticides because of its thigmokinetic behaviour and resistance to insecticides.

Development and fecundity were investigated in an invasive alien thrips species, Frankliniella occidentalis (Pergande), and a related native species, Frankliniella intonsa (Trybom), under high CO2 concentration. Results show that the two thrips species reacted differently toward elevated CO2 concentration. Developmental duration decreased significantly

Inheritance of resistance to acrinathrin in Frankliniella occidentalis (Thysanoptera: Thripidae)
Pest Management Science, 2008AbstractBACKGROUND: The western flower thrips (WFT), Frankliniella occidentalis (Pergande), is an economically important pest. The genetic basis of acrinathrin resistance was investigated in WFT.RESULTS: The resistant strain, selected in the laboratory for acrinathrin resistance from a pool of thrips populations collected in Almeria (south‐eastern ...

Cyantraniliprole: a valuable tool for Frankliniella occidentalis (Pergande) management
Pest Management Science, 2014AbstractBACKGROUNDFrankliniella occidentalis is a worldwide economically important pest. Scarcity of effective products and cross‐resistance issues make resistance to existing insecticides a recurring problem that requires the development of new control tools, such as incorporating novel compounds.

Rapid cold hardening in the western flower thrips Frankliniella occidentalis
Journal of Insect Physiology, 1997A rapid cold hardening process is reported in first instar larvae of Frankliniella occidentalis. When larvae are transferred directly from 20 degrees C to -11.5 degrees C for 2h there is 78% mortality, whereas exposure to 0 degrees C for 4h prior to transfer to -11.5 degrees C reduces mortality to 10%.

Invasion biology, ecology, and management of Frankliniella occidentalis in China
Archives of Insect Biochemistry and Physiology, 2019AbstractFrankliniella occidentalis is an economically important invasive pest worldwide, which can damage various horticultural crops and ornamental plants. F. occidentalis was first intercepted in Kunming, Yunnan province in 2000, and first reported to establish a population in Beijing, China in 2003.

Analysis of Anal Droplets of the Western Flower Thrips Frankliniella occidentalis
Journal of Chemical Ecology, 2003Larvae of the western flower thrips Frankliniella occidentalis are known to produce an anal droplet containing decyl acetate (10Ac) and dodecyl acetate (12Ac), which act as an alarm pheromone. Analysis by GC showed that the combined mass of 10Ac and 12Ac per droplet increased with age of second instars from 2 ng to 18 ng, while the mass ratio of 10Ac ...

RNA interference tools for the western flower thrips, Frankliniella occidentalis
Journal of Insect Physiology, 2015The insect order Thysanoptera is exclusively comprised of small insects commonly known as thrips. The western flower thrips, Frankliniella occidentalis, is an economically important pest amongst thysanopterans due to extensive feeding damage and tospovirus transmission to hundreds of plant species worldwide.

The vector competence of Frankliniella occidentalis for Chrysanthemum stem necrosis virus (CSNV) was evaluated. Three vector strains with distinct competences for Tomato spotted wilt virus (TSWV) transmission were investigated, including an artificially selected strain (TsH) that has a particularly high competence (>90 %).

Bionomics of Rose Thrips, Frankliniella Occidentalis Pergande
Journal of Horticulture, 2014A lab trial was conducted during 2012-13 at Department of Entomology, College of Agriculture, JAU, Junagadh to study the bionomics of rose thrips, Frankliniella occidentalis Pergande. Laboratory studies revealed that the female laid their eggs in the leaf tissues by sharp ovipositor. The average incubation period was found 5.28 day.
